 Purpose The industrial solution SU-302 is a converter which converts serial data to USB data. For this purpose, the device has one USB 2.0 interface and two serial interfaces: 1. RS-232 (for plug type D-Sub, DE-9) 2. RS-485 (also known as EIA-485; compatible with RS-422/ EIA-422) The SU-302 is connected to a client via the USB interface. Alternatively, the SU-302 can be connected to an industrial USB Deviceserver 'INU-100’ by SEH Computertechnik GmbH. This way, the serial devices which are connected to the SU302 can be accessed via a TCP/IP network or the Internet. The USB interface...

Industrial Solution 'IH-304 USB Hub' The industrial solution IH-304 is a USB hub with four USB 3.0 ports. Up to four USB devices such as the SU-302 can be connected to these USB ports and be used via one single USB connection. This is a most efficient solution for control cabinets with few free USB ports. The IH-304 in turn is connected to a client via the USB interface. Alternatively, the IH-304 can be connected to an industrial USB Deviceserver 'INU-100’ by SEH Computertechnik GmbH (’Industrial Solution 'INU-100 USB Deviceserver'’ 2). This way, the connected USB devices can be accessed...

 Safety Regulations The SU-302 is a data converter for use in industrial environments. The SU-302 converts serial data to USB data. • Read the documentation and make sure that your system meets the requirements listed therein. • Avoid contact with humidity or liquids. • The device must only be connected and operated if it is in perfect condition. • Do not open the housing. Unauthorized modifications to the device can affect the product certification and are forbidden. • Only use a certified USB cable (< 3 m) listed at www.usb.org. • Electrostatic discharges (ESD) may impair device...

 Preparation If you connect a serial device to a client via SU-302, the driver installation is the first step. Then the serial interface will automatically be enumerated as port on the client. The enumeration is dynamic, i.e. the serial interface receives the next available port number. Thus it is also client-specific. The serial device will keep the port number even if it is removed occasionally but connected back to the same physical USB interface. To identify the port numbers that the serial devices connected via SU-302 receive from the client, you must note down which port numbers are...

Linux In Linux serial devices connected via a serial to USB converter such as the SU-302 are enumerated as ttyUSB port. 1. Search the folder /dev for files with 'ttyUSB' in their name. 2. Note down the result. If no devices are connected, no files exist. Take a screenshot and save or print it. User Manual
